Elements in Tool Steel

-
In this article, we would like to discuss the elements that make up tool & high speed steels. What do these elements do to provide the mechanical and physical properties we need for our applications? The most common elements are the following:

CARBON (C): this is the most basic alloying element which enables steel to harden. Carbon combines with the other elements to form hard, wear-resistant carbides.

MANGANESE (Mn): controls hardenability in alloy cold work steels.

SILICON (Si): improves toughness in the shock resisting steels group. Added to hot work steels to raise critical points and reduce scaling tendencies. Added to O-6 & A-10 to form graphite.

CHROMIUM (Cr): controls hardenability and is added for abrasion resistance and hot hardness.

TUNGSTEN (W): provides red hardness and hard wear resistant carbides that are harder than chrome and iron carbides. Also used to improve hardenability in tool & high speed steels. Combines very well with molybdenum and vanadium.

MOLYBDENUM (Mo): molybdenum has double the potency of tungsten to provide red hardness resistance. Added to steels to improve hardenability.

VANADIUM (V): provides red hardness resistance. Vanadium carbides are harder than and more abrasion resistant than other carbides. Contributes to grain refinement when added in small quantities. Combines very well with other carbides.

COBALT (Co): greatly improves red hardness. Cobalt does not combine with other carbides as it does not form carbides and remains in solid solution.

AISI 8620 Steel | 1.6523 | 21NiCrMo2 | SNCM220

AISI  8620 Steel  is a low alloy nickel, chromium, molybdenum case hardening steel, generally supplied in the as-rolled condition with a maximum hardness of HB 255max. SAE steel 8620 offers high external strength and good internal strength, making it highly wear resistant. AISI 8620 steel has a higher core strength than grades 8615 and 8617. SAE 8620 alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties. Pre-hardened and tempered (un carburized) 8620 can be further surface hardened by nitriding but will not respond satisfactorily to flame or induction hardening due to its low carbon content. Steel 8620 is suited for applications which require a combination of toughness and wear resistance. This grade is commonly supplied in round bar. 1. AISI 8620 Steel Supply Range 8620 Round Bar: diameter 8mm – 3000mm 8620 Steel Plate: thickness 10mm – 1500mm x width 200mm – 3000mm 8620 Square Bar: 20mm – 500mm 8620 tubes are also availabl

M2 Tool Steel | 1.3343 | HS-6-5-2C| SKH51 AISI  M2 Tool Steel  is molybdenum based high-speed steel in tungsten–molybdenum series.  HSS  grade steel  M2  is a medium alloyed high speed steel which has good machinability. The H-SS M2 chemical composition gives a good combination of well-balanced toughness, wear resistance and red hardness properties. Widely used for cutting tools such as twist drills, taps, milling cutters, saws, knives etc. Also commonly used in cold work punches and dies and cutting applications involving high speed and light cuts. Grade M2 High Speed Steel is by far the most popular high speed steel replacing high speed steel grade  T1  in most applications because of its superior properties and relative economy. We are one of leading AISI M2 HSS steel supplier and we can offer better quality and M2 alloy steel price for your various applications. 1.

What Do YOU Know About Mold Steel Quality?

Many industries place strict requirements on the acceptable level of surface defects and imperfections that may appear on a plastic molded part. Such conditions often apply to critical components for the medical and pharmaceutical industries as well as for the manufacturers of lenses and other optical devices. However, for aesthetic reasons, many other consumer goods have similar restrictions. After all, any defect that appears on the surface of the mold steel is likely to be replicated onto the molded part. Problems associated with the texturing or polishability of a mold cavity can often be traced back to the mold steelmaking process. The material properties that have shown the greatest influence on obtaining a good surface finish are the microcleanliness level, the severity of chemical segregation and the appearance of primary carbides. The mold steel's chemical composition along with the manufacturing techniques used during its production, will determine its ability to p
